Shin-Hyun Kim,* Su Yeon Lee, and Seung-Man Yang* Inspired from superhydrophobic small objects, such as the scales of butterfly wings and the legs of water striders, we created Janus microspheres composed of superhydrophobic and hydrophilic hemispherical surfaces using photocurable Pickering emulsion droplets of equal size. When placed at an air–water interface, these Janus microspheres form a highly flexible monolayer with the hydrophilic hemispheres facing the aqueous phase. Such Janus particle layers can form an impregnable superhydrophobic barrier at the interface. The Janus microspheres have great potential in size-dependent semi-permeable membranes, buoys for floating micromachines, and various superhydrophobic coatings, for example in rain-resistant makeup. Erscheint demnächst. |
